Researchers found a link between childhood deprivation, impulsive behaviour and addictions later in life Behaviours include overeating, taking drugs, smoking cigarettes and gambling A second study found adults living in deprived areas displayed similar impulsive traits Children who have experienced deprivation are more likely to make more impulsive choices than those who don’t and can lead to addictions in later life research has shown. ‘Trait impulsivity’, the preference for immediate gratification, has been linked to spending more on food, especially unhealthy, highly calorific food. Studies have shown that children who experience poverty and food insecurity tend to have a higher body-mass index as adults than those who do not. Researchers from the School of Psychology at Aston University found a link between deprivation in childhood and impulsive behaviour – leading to addictions later in life. The findings, which are a culmination of six years of research, also found a further link between impulsivity, obesity and the cost of living crisis. Professor Richard Tunney, head of the School of Psychology at Aston University, published a study in Scientific Reports earlier this year where he showed that children who experience deprivation make more impulsive choices than children who don’t. The research team studied 146 children, with an average age of eight, living in some of the most deprived areas of England and compared them with children living in some of the most affluent neighbourhoods. Children were given a choice between taking home a small amount of money (for example, £1) or getting £10 a week, or even more a year later. How long a person is willing to wait for the larger amount of money can be used to calculate a ‘discount rate’ that shows how much the waiting time reduces the value of the money. An impulsive person might prefer £1 now because the value of £10 in six months is ‘discounted’ to less than £1 right now. This means that, for them, the £10, is discounted by £9 over the six-month wait. A less impulsive person might be willing to wait six months for £10, but not wait for a whole year for £15. This means that, for them, the value of the £15 is discounted by £5 over the additional six-month wait. This discount rate is a measure of how impulsive someone is. Commenting on the findings, Professor Tunney said: “The results showed that children living in the most deprived areas had significantly higher discount rates than children living in the least deprived areas, regardless of age or intelligence, indicating that deprivation was the causal factor in the children’s choice. “This preference for immediate outcomes is a stable personality trait that remains constant throughout a person’s life.” However, in the research team’s most recent study published by the Royal Society, they investigated impulsivity in over 1,000 older adults aged between 50 and 90. The study found that older adults living in the most deprived areas showed the same preference for smaller-sooner financial outcomes as the children in the first study. It also found that a person’s job predicted the choices they made. Adults working in technical or routine occupations, such as mechanics or cleaners, chose to receive smaller amounts of money than wait for larger amounts compared with people in professional occupations, such as engineers or scientists. Professor Tunney added: “These findings are concerning because impulsivity doesn’t just predict obesity. These findings tell us a lot about why people living in poorer areas tend to be unhealthier than people living in wealthy areas. “People who experience deprivation as children are more likely to choose to do things that, although they might be pleasurable in the short term, are unhealthy in the long run. This includes overeating, taking drugs, smoking cigarettes and gambling. “We know too, that impulsivity can help to explain why some people go on to become addicts, while other people can avoid some of the more harmful effects of drugs and alcohol. “Deprivation is one of many factors that can lead to impulsive behaviour throughout a person’s lifetime. Genetics also plays a role in impulsivity. Policymakers can’t do anything about a person’s genes but they can influence the nation’s long-term mental and physical health by minimising child poverty. Failing to do so will have long-term implications for the children living through today’s cost of living crisis.” For more information about the School of Psychology at Aston University, please visit our website.

Inflation is running high around the globe, largely fuelled by Russia’s war in Ukraine and the COVID pandemic. As a result, many households are having to choose between eating and heating. Deprivation has a terrible immediate effect on children – as anyone who has experienced real hunger knows – but it can also affect things like impulsive behaviour in later life. “Trait impulsivity”, the preference for immediate gratification, has been linked to spending more on food, especially unhealthy, highly calorific food. Studies have shown that children who experience poverty and food insecurity tend to have a higher body-mass index as adults than those who do not. In a study published in Scientific Reports earlier this year, my colleagues and I showed that children who experience deprivation make more impulsive choices than children who don’t.

Children were given a choice between taking home a small amount of money (for example, £1) or getting £10 a week, or even more a year later.

Aston University has teamed up with Alpharmaxim Healthcare Communications to apply the latest behavioural psychology research to develop a unique prescribing behaviour tool for healthcare professionals. At present there is a growing recognition in the healthcare sector that measuring belief change and/or intent to change behaviour can determine the effectiveness of marketing campaigns. The Healthcare Belief-Barrier Identification Tool (H-BIT)will identify beliefs and barriers in prescribing behaviour of EU healthcare professionals in specific disease areas, enabling targeted communication strategies that maximise the reach of treatments. Alpharmaxim is a long-established specialist marketing communications agency in the healthcare sector that helps pharmaceutical companies create effective communication plans for their products or services. A Knowledge Transfer Partnership (KTP) is a three-way collaboration between a business, an academic partner and a highly qualified graduate, known as a KTP associate. The UK-wide programme helps businesses to improve their competitiveness and productivity through the better use of knowledge, technology and skills. Aston University is the leading KTP provider within the Midlands. This KTP will combine Alpharmaxim’s rich history of harnessing behavioural psychology through their Belief Continuum® (BC) model with Aston University’s expertise in Nominal Group Technique (NGT), a structured method for group brainstorming that encourages contributions from everyone and facilitates quick agreement on the relative importance of issues, problems, or solutions. Applying NGT to objectively evaluate beliefs and behaviours that underpin behavioural change in a defined disease area will be unique in this field. The academic team from Aston University will be led by Dr Carl Senior, reader in psychology at Aston University. Dr Senior is a behavioural scientist with 20 years’ experience working at the interface between social psychology and organisational behaviour and was one of the first to develop a framework for applying NGT to understanding effective behaviour change. Commenting on the project, Dr Senior said: “We are delighted to have this opportunity to work with Alpharmaxim in this strategic relationship to lead change that is both focused and relevant to modern day health care.” Dr Senior will be joined by Dr Jason Thomas, senior lecturer in psychology at Aston University. Dr Thomas has spent the last ten years investigating novel approaches to encourage behavioural change, working with companies such as Direct Line and Starbucks to encourage their employees and customers to eat more healthily. William Hind, founder, controlling director and agency principal at Alpharmaxim, said: “We are delighted to be involved with this innovative KTP and hope the partnership will change the face of healthcare communications, ultimately improving the lives of patients with hard-to-treat diseases.”
